Passkeys replace typed passwords with a cryptographic credential stored on a trusted device or password manager. People sign in using a fingerprint, face, or device PIN, and the secret itself is not sent to the website.
Why passkeys resist phishing
A passkey is tied to the legitimate website. A convincing fake login page cannot capture a reusable password because there is no shared secret for the user to type or reveal.
What the user experiences
Signing in usually looks like unlocking a phone or computer. Depending on the platform, passkeys can synchronize securely across a person’s devices or be stored on a hardware security key.
Adopt them thoughtfully
Start with important services that support passkeys, maintain secure recovery methods, and document offboarding. During the transition, keep strong MFA and password-management practices in place for systems that still require passwords.

Passkeys make strong authentication easier for users while removing the phishable password from the sign-in flow.
